CAR-COUPLING.

SPECIPICAI'IQN forming part of Letters Patent No. 323,752, dated August 4, 1885.

Application filed January 521, 1885. (N model.)

To all whom/ it may concern.-

Be it known that I, DAVID STURGIS, of Harrison, in the county of Clare and State of Michigan, have invented new and useful Improve- Inentsin Car-Oouple rs; and Ido hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and novel improvements in the construction of antomatic car-couplers.

The invention consists in the peculiar construction of the draw-head, the same being in I 5 two parts pivotally secured together, the lower part being rigidly secured to or forming a part of the draw bar, and is provided with a rigid hook to engage with the link; in the peculiar construction and arrangement of the upper section, and means provided for uncoupling, and in the peculiar construction, arrangement, and combination of the various parts, all as more fully hereinafter set forth.

Figure 1 is a perspective view of one end of a car provided with my improved coupler. Fig. 2is a side elevation ofone coupler, opened, and also a vertical longitudinal section through the fellow coupler, opened.

In the accompanying drawings, which form a part of this specification, A represents a drawbar, which is designed to be secured to the car B in any of the known ways. The draw-bar is'provided with the draw-head O, which is formed in two parts, a b, the upper 3 5 part, a, being pivotally secured to the part b in any convenient manner. When the parts are closed, they form a complete draw-head provided with the usual mouth and throat to receive a link.

At the throat of the lower part, b, there is formed an upwardly-projecting stud or tooth, D, the outer face of which inclines to the rear, while its rear face is nearly vertical. WVhen the head is closed, the point of this tooth en- 5 ters a recess, a, in the upper portion of the head.

To the under face of the part a there is secured an arm, d. E isarod journaled in proper brackets on the end of the car-sill, and is provided with a bail or crank, F, at its longi- 5o tudinal center, which engages with a bale, G,

on the outer face of the part a of the coupler.

This rod E is also provided with a handle, H, at each end.

In practice the link of an approaching car enters the mouth of the opposing coupler, slides up the inclined face of the tooth D, at the same time radially raising the upper part of the coupler until the link, by its gravity, falls behind the tooth, when the upper part of the draw-head assumes its original position and the two are coupled together.

To uncouple, the operator turns the rod E so that its bail will raise the upper section of the draw-head,while atthe same time the arm d raises the link so that it is readily with drawn. If it is desired to adjust the device so that it will not couple when two cars come together, the upper section is raised, as described, and the rod E pushed sidewise till its bail rests upon the stop I.

What I claim as my invention is 1. In a car-coupling, a horizontally-divided draw-head having its lower section stationary and its upper section or jaw pivotally secured thereto, in combination with the crank-shaft F, adapted to be thrust laterally,and with the rest I, all arranged substantially as described.

2. In a car-ooupling, a horizontally-divided draw-head having its lower section stationary and its upper section or jawpivotally secured thereto, a rearwardly-inclined tooth, D, in the lower section, a stop with a projecting arm in the upperjaw, a crankshaft engaging with a loop or bail on the upper jaw, and a rest, I, all arranged and operating substantially as described.
